We measured the frequency of appearance of spontaneous mutants resistant to gentamicin, kanamycin, streptomycin, and spectinomycin in saprophytic and pathogenic Leptospira strains. The mutations responsible for the spontaneous resistance to streptomycin and spectinomycin were identified in the rpsL and rrs genes, respectively. We also generated a gentamicin resistance cassette that allows the use of a third selectable marker in leptospires. These results may facilitate further advances in gene transfer systems in Leptospira spp.

is a bacteria responsible for a widespread zoonosis that affects both humans and animals. Leptospirosis is a challenging pathology to diagnose and treat since its signs are unspecific and symptoms vary greatly. The disease seems to be highly prevalent in environments where reservoir animals such as rats and small mammals are common.

Background And Aim: Leptospirosis is an infectious zoonotic disease that significantly affects animal health, particularly the reproduction of ruminants. However, some aspects of epidemiology and clinical characteristics have not been clarified. This study aimed to estimate the prevalence and identify risk factors of leptospirosis in female bovines at reproductive age in the Ecuadorian Amazon rainforest.

The black rat Rattus rattus is an exotic and synanthropic rodent prominent in Brazil and with high adaptation to urban areas. The species have an omnivorous diet feed on human food resources, potentially becoming infected and spreading infectious agents that cause zoonoses such as leptospirosis, leishmaniosis, Chagas disease, and toxoplasmosis, which are significant public health concerns in the country. We analyzed the epidemiologic profile of R.
